Einstein Supergravity and New Twistor String Theories
Mohab Abou-Zeid, Christopher M. Hull, Lionel J. Mason
A family of new twistor string theories is constructed and shown to be free from world-sheet anomalies. The spectra in space-time are calculated and shown to give Einstein supergra…

A Chiral Perturbation Expansion for Gravity
M. Abou-Zeid, C. M. Hull
A formulation of Einstein gravity, analogous to that for gauge theory arising from the Chalmers-Siegel action, leads to a perturbation theory about an asymmetric weak coupling limi…

Actions for Curved Branes
Mohab Abou-Zeid
The nondeterminantal forms of the Born-Infeld and related brane actions in which the gauge fields couple to both an induced metric and an intrinsic metric are generalised by lettin…
